The data below represent a cohort of organism “X”, tracked from birth to death. Time period* Number alive at start of period Proportion surviving at start of time interval Deaths during period Rate of mortality during time period "0-1" 432 1.00 390 0.90 "1-2" 42 0.10 29 0.69 "2-3" 13 "3-4" 11 "4-5" 10 "5-6" 9 "6-7" 7 "7-8" 3 "8-9" 0 * Numbers are reported over eight equal sized time periods – these could represent days, weeks, months or years. 1.Complete the table by recording survivorship (proportion alive at the start of the time period), the number of deaths and the mortality rate for each time period. For each column you need to ensure you indicate how you performed your calculation (e.g. show one example calculation or provide a formula). 2.Plot a survivorship curve for species X using semi-log graph paper.Remember that survivorship is, by convention, plotted as a proportion of…
